You have right. Thanks for the Info. I knew it, read it somewhere, but I forgot it.
I wanted a full Ubuntu Unity experience with the old good looking LightDM (unity-greeter), but you have right about Wayland session it is not working through LightDM.

This is where there may be a demarcation line in this development cycle. By Feb the devs will be looking to focus on gdm3 as the default. I had heard mention that lightdm may be done away with. I have to be honest … this is one scenario that I can’t crystal ball.

As big of a Unity 8 fan as I am, I don’t think adding Qt dependencies in the Ubuntu desktop should be an option. Otherwise, we would probably be using Dolphin right now, as Dolphin seems more compatible with Unity 7 than the current Nautilus (it works with both Global Menu and LIM) and I’ve seen it running under Unity 8 too with LIM (though Unity 8 is a Qt desktop). I thought what we are doing here is testing Unity 7 with the default apps in the Ubuntu default .iso and hunt for bugs / glitches.

All the Unity 8 apps are great, I might help Ubports after we make 18.04 Unity a good, non-broken LTS. Even now, I’m currently ultra part-time tester here.

I was testing the latest build from Dec. 27 /17 on a touch device Acer mobile laptop. It worked perfectly with workspaces enabled and i could drag apps through the screens but then it booted into modesetting and now compiz workspaces will lock up. Otherwise it works very well with standard desktop.https://www.youtube.com/watch?v=_eL4vb17GQ4&feature=youtu.be

I’m seeing almost no issues to date with unity in 18.04 though it’s still early.
One issue is likely not just on unity though more easily exposed. It’s that some menu dropdown options are light until moused over, can be seen in ccsm pretty easily. But I’ve also seen in default 18.04 like in a debconf popup about which version to keep…

What is an issue is that alt+print does not work properly, here it either prints the entire desktop or the hud command box.
I’ve a local fix by integrating gnome-screenshot -w as a compiz command, binding command to alt+print & disabling alt+print in gnome-settings-daemon.
A more proper fix would be good.

My Bionic Unity with your ppa bionic-prop works pretty well with Nemo, and without Nautilus (uninstalled). Unity Tweak is there and with full Compiz eye-candy. Hope you’d keep that ppa upgraded. Thanks!
